We also computed analogs focusing only on the impacted region, but the large-scale circulation pattern was quite different from the event, so much that one wonders if it was still the same event.

A question about causality: are the oceans intensifying heat inland, or are they warming as a result of the same circulation inducing heat over land? The second pathway is clear, the first not immediately obvious as sea temperature is less than land air temperature.

Yes and indeed these bullet points about inertia are nowhere to be found in the English version of Red Electrica.
Still interesting, however, that everything seems to have started from a solar power plant... and the exact cause not been found yet.
Interestingly yes, it seems. This is an excerpt from the conclusions (in Spanish, but I think the first sentence is still understandable).

One of a meteorologist’s biggest pet peeves is “my app says it’ll be ____”. Weather apps can miss so many details that a meteorologist will know.

Interesting read!
There are many neopositivist and even "messianic" expectations about AGI, I hope we will soon have more realistic expectations about that "bubble", too.
It's no exaggeration to say today brought a truly historical weather event to the Gulf Coast - lots of places all the way down to the water got over 6-8 inches of snow, shattering records going as far back as 1895 in some places.
Let's review what caused this historic event 🧵
This drastic circulation change indicates that the large-scale flow configuration has to be fully reconfigured over the North Atlantic after the cold spell.
Does such a pattern shift happen as a result of the cold spell, or is the cold spell a byproduct of it? That's an open question imo. (4/4)
The risk of windstorms over the North Sea region remains significantly high up to 7-10 days after the cold spell.
This is consistent with the zonal flow pattern expected in the next few days over the North Atlantic and "seen" by medium-range models. (3/4)
